Description

Hinge for central armrest box of automobile

Technical Field

The utility model belongs to the technical field of automobile parts, concretely relates to central armrest box hinge of car.

Background

The central armrest box is usually located between the car seats on both sides, typically between the front driver seat and the front passenger seat, and can provide elbow support for the driver and passengers, and can also place small articles such as certificates in the box body after the box cover is lifted. The central armrest between the front and the rear passenger seats is conventionally called a front central armrest, and has a cup holder function by being provided with a cup holder component in addition to the two functions. In addition, a cup holder and/or a storage box are also arranged on the center armrest of the rear seat of a part of vehicle types. And a man-machine interaction system is integrated on the central armrest of some luxury automobiles so as to operate back row audio and video equipment, and the like. It is understood that the center armrest of the automobile is not absolutely limited to the center armrest of the cab.

Technical information related to the center armrest box hinge of an automobile, such as CN205522816U (automobile armrest hinge device), CN204821226U (folding hinge mechanism of automobile center armrest), and CN204586580U (automobile of an armrest hinge device), etc., can be found in published chinese patent documents. Not limited to the exemplified drawbacks of the aforementioned patent are eliminated by CN206394486U (armrest hinge structure for automobiles), and CN206394486U objectively embodies the technical effects in the four aspects described in the technical effect column of the specification thereof, but has disadvantages such as relatively complicated structure of the hinge mechanism and relatively large volume of the whole hinge system composed of the upper hinge bracket and the lower hinge bracket, which is disadvantageous to reasonable space saving.
